Bitcoin’s Core Design: Fixed 21 Million Supply, Peer-to-Peer Ledger Without Central Authority

This is an explainer rather than a news event, so its value lies in framing: the scarcity and Proof of Work model it describes is the reference point against which every later digital asset is measured, and that matters most for readers assessing tokens that claim similar properties. The piece's real emphasis is on the ledger being maintained without a central operator, which is the distinction that separates Bitcoin from custodial or permissioned systems. The open question, for anyone comparing assets, is whether a given network genuinely replicates that arrangement or only borrows the language.
